IWA-CHINE FOR CRIVIPING TOBACCO. I

Speciiication forming part of Letters Patent No. lih. dated April 6,1858.

and useful Apparatus for Crimping Rolls'of- Iobacco Previous to Pressingin the Process of vManufacture; and I do hereby describe and ascertainsaid invention in the following 'description and accompanying drawings,in which- -Figurelisatop plan;A Fig. 2, avertical longitudinal sectionon the line x :r of Fig. l, Fig. 3, a roll of tobacco.

In the manufacture of chewing-tobacco into lumps, 7 it is first formedinto rolls by hand, as seen in Fig. 3, after which, by the processheretofore employed, each roll is placed in apress upon a board. W'henone board is covered properly with rolls, another board is laid uponthem and covered with a layer of rolls like the first, to be succeededby another board, and so on until the press'is full, when by an ordinaryscrew and lever the whole is flattened as much as possible by thesemeans, after which the operation is completed by pressing each lump in amold. It will be obvious that the method above described will notproduce a thin flat lump of equal density but there Will at the centerbe too much material and at the edges a deficiency. Many evils arisefrom this cause, for if the lumps are dense at the center and loose -andspongy at the edges'they will, when packed in boxes, soon become moldyor unsound; besides, the appearance ofthe article is very inferior towhat it would be if the whole lump were of equal density. To obviatethis defect I first devised a convex follower, so as to press down morein the center, and thus crowd the material toward the edges. 'llhispartially improved the manufacture, but did not `sufciently equalize theroll, especially lengthwise. I have therefore made the presentapparatus, which practically removes all the important defects ofprevious methods and prepares the lumps sufficiently for the lastprocess.

The construction of my machine for crimping is as follows: In a suitableframe, a, I place one or more pairs of rollers, (I have found threepairs, as in the drawings, to produce, in

most cases, a sufficient result,) with a guiding -trough, to conduct therolls of tobacco thereto, and from them onward to any number of pairs ofrollers the machine may contain. In the drawings, b b is the irst pairof rollers. The top plan shows these rollers to be eonveXed on theirsurface and rounded off toward their edges. c is the trough throughwhich the roll passes between said rollers b b, by which the roll isiiattened and the material somewhat equalized and crowded outward towardthe edges. Thence the lroll may be made to pass through another similarset, i, and so on, care being taken to decrease the distance a little ofeach pair, and not to have so great a number as to break or injure vthesurface-wrapper. The last pair of rollers should be dat-surfacedcylinders, or only very slightly convex. The rollers are all gearedtogether', with intermediate gear, d, between the pairs, to cause themall to revolve in the proper direction, obviously necessary to producethe result.

/Vith this machine one hand can crimp 4a much larger amount than severalby the old system, and the work is much more perfectly done. The lastpair of rollers can be set aecording to thel material worked.

Having thus fully described my crimpingmachine, what I claim, and desireto secure by Letters Patent, is-

The employment of one or more pairs of rollers, constructed and arrangedsubstantially as above set forth, for equalizing and crimping rolls inthe manufacture of lump-tobacco.

In testimony whereof I have hereunto set my hand.
